Car won't turn on after expansion tank replacement

As simple as that, I had the battery charged at an autozone so I doubt there's a problem with that.

The dash and all the lights turn on as well as the fan.

There's a click, no other noises.

I'm going to buy and test a new battery, but does anyone know a solution?

Thanks
 
Starter? Does it start if you bump start it? My starter went but it would still start if it was bumped. If you've diagnosed starter, sometimes as firm gentle tap with a mallet can un-seize it
 
I had no luck with a jump start and hitting the starter didn't help,

I looked at the other post but I'm wondering if the expansion replacement was part of the problem.
 
Cheapest fix attempt is measuring with a multimeter if the starter gets any voltage on the motor and if the relais is working :wink:

Its always best to first diagnose.
My guess its worn out brushes on the starter, as he describes there's a click.

You can get the brushes seperately if the starters' commutator is still alright:

(swapping these brushes out when buying a used starter is also a good idea, as all these starters die after about 10-15 years from worn out brushes)
 
Thanks for the help guys, and by any chance could the car be disprogrammed from having the battery disconnected?

I had a mechanic over who told me a special tool needed to be plugged in to prevent that from happening.

I wasn't sure if that was the situation with this car, and I'll look into getting a starter.

Thanks
